Answer: The answer is obviously True!!!!
Explanation: The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects. ... However, the exponent on the mass terms is one.
Answer:
22 N
Explanation:
The box is moving, so there is kinetic friction.
The speed is constant, so there is no acceleration.
Draw a free body diagram of the box. There are four forces.
Normal force Fn pushing up.
Weigh force mg pulling down.
Applied force F pushing right.
Friction force Fn μk pushing left.
Sum the forces in the y direction:
∑F = ma
Fn − mg = 0
Fn = mg
Sum the forces in the x direction:
∑F = ma
F − Fn μk = 0
F = Fn μk
F = mg μk
F = (11.2 kg) (9.8 m/s²) (0.200)
F = 22.0 N
